I checked the novel, and here's a mention of tsunami: "It wasn't enough that the ministry fell; the impact caused the volcano that was the heart and namesake of Vvardenfell to explode. Ash, lava, and tidal waves had done their work, and when that was calmed, the Argonians had come, eager to repay what survived of his [Sul's] people for millennia of abuse and enslavement. Of course, those that had settled in southern Morrowind were likely regretting it now, as Umbriel moved over their villages." (p. 261)
Later, Sul says to the character Vuhon that the latter had " . . . destroyed our city and our country, left our people to be driven to the ends of the earth." (p. 276)
Those are good points about possible teleportation or sailing away from Morrowind, though. I hope we find out more in the second novel and in TES V as to whether Helseth died and how many other Dunmer survived.
Thanks syronj - I guess the author meant shockwaves
- even if the 'rock' was called a moon.
I have a feeling that despite picking many neat points of Lore Greg Keyes played fast and loose with his descriptions and I bet some devs were fuming and very anxious to get key stuff in ^^
As for Umbriel that looks to be a comparatively gradual process. Can we assume that a substantial number of the population survived to leave the former Province. How fast did Umbriel travel? How many dunmer were able to walk/teleport/run/lev/ride/sail out of it's way and remain in Morrowind?
Mind you when did the Argonians arrive? After Umbriel had left? Not if I read your quote aright - they arrived before Umbriel so were they caught by it too?
The damage to Morrowind as a whole from Umbriel appears to be from disruption to the normal and delicate workings of the country and the shock = a breakdown in the normal provision of the basics needed to support a civilisation as much as the numbers killed by the thing.
All in all I am not yet certain Mr Keyes is fully aware of the difference between playing ES and writing his own books. Wish he had been an ES player.
ps - seem to remember that the most massive damage comes from a volcano when there is an eruption followed by an explosion. The way it works - as with Krakatoa is that when there is a massive breach of the volcanoe's wall and the ocean rushes in = superheated steam and that then provides the force+++ but that does not appear to be the case here. Vvardenfell is a huge island. It has a very substantial bedrock. and the cone of the volcano is thousands of feet above the waterline. So we have a massive eruption with Red Mountain's cone being far too high above the sea to let it in. It is not a caldera.
Anything far enough out to sea would have had a good chance to survive the tsunami as it is when a tsunami reaches a coast that it gets most destructive
If there had been a massive breach of the cone sufficient to let in the ocean there would likely have been no sea left ^^ and yeah there would have been a 'nuclear winter' so it was more a massive eruption that did the damage except to Vivec itself. I expect the the impact of the rock and that would have caused a Tsunami - that would have been directed southwards. So perhaps the impact caused a tsunami which would have travelled south - out towards the mainland. Water would have been drained from the beaches of the Island ... oops and Solstheim would have been in trouble too if the Mainland was ... and then water would have rushed back in. Aaargh.
Shocks from the volcano may have been different. Hard to judge that
I would imagine the shock of that impact upset the balance within the volcano to such an extent that the resulting eruption was far more severe than previous instances so this time the effects were not limited to the ashlands. There could have been an explosion if sufficient build up of gasses and such had been taking place within the volcano. fortunately for our dreams that would likely have left an area uninhabitable for some time but partially recognisable.
